Claims
1. A Modular Core Block Construction in firearms, comprising: a
frame as a means for the barrel assembly to open and close and for
the modular core block assembly to attach to it, a modular core
block assembly as a means to contain necessary components to open,
close, and fire said firearm, whereby said firearm can be
manufactured and serviced easier and have parts repaired or
replaced to extend said firearm's useful life.
Description
BACKGROUND
[0001] 1. Field of Invention
[0002] This invention relates to firearms and the use of a modular
core block construction.
[0003] 2. Description of the Related Art
[0004] Firearms with break-open frames have traditionally been
manufactured as a single piece with complex machining of firing pin
holes, relief's for springs and action components necessary to
hollow out a solid block or forging. The numerous setups to
complete a frame reduce the weight from a 3 to 5 pound piece of
steel down to less than 2 pounds. If any one operation is out of
tolerance then the frame is ruined.
[0005] This invention improves on firearm frame manufacture and
prior art by modularizing the frame into a frame and a rebuild-able
modular core block assembly. The modular core block assembly
contains the core block face, firing pins, firing pin springs and
other components. As such the modular core block can be
manufactured separately from the frame using different materials
that optimize each part's strength and performance. It's size and
shape simplifies the manufacturing process.
SUMMARY OF THE INVENTION
[0006] This invention improves on firearm frame manufacture by
modularizing the frame into a frame and modular core block
assembly. The modular core block assembly contains the firing pins,
firing pin springs and other components. It is manufactured
separately from the frame and due to it's size and shape can be
more easily made. Once assembled it slides into the frame and is
designed to withstand all pressures produced from firing the gun.
If parts break within the module or wear out, the parts that fail
can be repaired without replacing the frame.

DETAILED DESCRIPTION OF THE INVENTION
[0026] This invention improves on firearm frame manufacture by
modularizing the frame into a frame and modular core block
assembly. The modular core block assembly contains the firing pins,
firing pin springs and other components. It is manufactured
separately from the frame and due to it's size and shape can be
more easily made. Once assembled it slides into the frame and is
designed to withstand all pressures produced from firing the gun.
If parts break within the module or wear out, the parts that fail
can be repaired without replacing the frame.
[0027] FIG. 1 is a perspective view of the frame and modular core
block construction. The frame 1 is illustrated with the modular
core block assembly 2 in place in the firearm.
[0028] FIG. 2 is an exploded view of the frame and modular core
block construction. The frame 1 is illustrated with the modular
core block assembly 2 removed from the firearm. The Frame relief
for modular core block assembly 1A is illustrated in this view and
is a negative form of the modular core block assembly shape so that
the assembly can slide into the frame 1 and fasten in place. The
modular core block face 2B clamps onto the frame 1 and keeps it
securely in place in the frame by sandwiching the frame relief for
modular core block assembly 1A between the modular core block face
2B and the modular core block buttress 2H.
[0029] FIG. 3 is a cross sectional view of the modular core block
assembly that illustrates how key parts of the assembly are
positioned for use. The modular core block assembly 2 is comprised
of: modular core block 2A, modular core block face 2B that has
holes for the firing pins to go through to ignite the primer in the
shell when firing the gun, the firing pin transfer plate 2C and the
transfer pin 2F transfer the energy form the gun's hammers when
firing the gun to ignite the shell's primers thereby firing the
shell, the firing pin transfer plate return spring 2D and firing
pin transfer plate pin 2E allow the firing pin transfer plate 2C to
swing forward to ignite the shell and retract under spring force
after firing the shell, and the modular core block assembly screws
2G. The lever pocket 2I that holds the firearm's lever that allows
on to open and lock close the firearm when unloading, loading and
firing the gun.
[0030] FIG. 4 is an exploded view of the modular core block
assembly provides a more detailed view of each part of the
assembly. Components 2A through 2I are the same as in FIG. 3 with a
more detailed view of the firing pin transfer plate return spring
2D showing the torsion spring that brings the firing pin transfer
plate pin 2C back to a neutral position after the gun is fired. The
nature of the exploded view of the modular core block assembly
provides a view of the modular core block transfer plate pin hole
2J that holds the firing pin transfer plate pin 2E that the firing
pin transfer plate 2C rotates on. When servicing the gun, the
firing pin transfer plate pin 2E is removed by using a drift punch
inserted through the modular core block drift hole 2K to drive the
pin out. The modular core block relief for transfer plates &
transfer pins 2L that house the firing pin transfer plate 2C and
transfer pin 2F. The modular core block buttress 2H is shown
clearly in this figure and was explained in the FIG. 2
narrative.
[0031] In summary the advantages of the modular core block
construction are: ease of manufacture, easier servicing and repair
or replacement of parts for a longer life firearm.
